5. Calculating the Pearson correlation and the coefficient of determination
5. Calculating the Pearson correlation and the coefficient of determinationSuppose you are interested in seeing whether the total number of days students are absent from high school correlates with their grades. You obtain school records that list the total absences and average grades (on a percentage scale) for 80 graduating seniors.You decide to use the computational formula to calculate the Pearson correlation between the total number of absences and average grades. To do so, you call the total number of...
